进口压力管道阀门型式试验规则探讨

Discussion of Type Test Rules for Imported Valves Used in Pressure Pinping

近年来,越来越多的进口压力管道阀门在工程中使用。介绍了进口压力管道阀门型式试验基本流程,如试验准备,设计审查、取样、试验项目、性能要求及覆盖范围等,还比较了进口阀门与国内阀门的制造标准和测试要求,并探讨了型式试验工作中的问题,以帮助国外阀门制造商更清楚地了解中国的法律、法规和工作流程,以确保产品的质量和保护用户的安全。

Recently more and more imported piping valves are applied in China. In this article, the type test procedure for imported valves used in pressure piping in China was introduced, including test preparation, design checking, sampling, testing items, characteristic requirements and covering scope. Also the manufacturing standards and testing requirements for imported valves and domestic made valves were compared. The issues in type test were discussed. With what presented herein, valve manufacturers and providers can know Chinese laws, regulations and working procedures more clearly, so that the quality of the products and the safety of the users can be ensured.
